Nekkhamma is a Pali word found in Buddhism, often translated as "renunciation" or "the pleasure of renunciation." Nekkhamma is about cultivating a sense of non-attachment, particularly to sensual pleasures and cravings. It's about recognizing that true happiness comes from letting go, not acquiring. Traditionally, renunciation is associated with monastics who devote themselves to spiritual pursuits. However, the concept can apply to anyone who chooses a simpler, more mindful way of living.
